I JOSEBH S. DUNCAN AND ULYSSES G. LEE, OF CHICAGO, ILLINOIS, A SSIGNORS TO .ADDRESSOGRAPI-I COMPANY, OF CHICAGO," ILLINOIS, A CORPORATION OF ILLINOIS.

To aZZ whom it may concern:

Be it known that we, Jo'sErH S. DUNCAN and ULYssEs G. LEE, citizens of the United States, both residing at Chicago, in the county of Cook and State of Illinois, have jointly invented certain new and usefulImprovements in'Stencil Addressing-Machines, of which the following is a specification.

This invention relates to printing machines and more particularly to a machine for printing addresses and information of a similar character from stencils.

Machines ofthis general character heretofore suggested or used have been subject to several disadvantages, amongwhich are the failure to distribute the ink uniformly this purpose by the provision of. means whereby uniform application ofth'e. ink to the stencil is assured in every instance. A further object of our invention is the provision of a machine of simple and inexpensive construction whereby the operator by a simple adjustment is. enabled to, obtain one or more impressions from-individual .stenoils without the necessity of manipulating the stencils.

Other objects and advantages of our invention will be apparent as it is better understood by reference to the. following specification when read in connection with the accompanying drawing illustrating the preferred embodiment thereof in which Figure 1 is aplan view of the machineaccording to our invention;

Fig. 2 is a side elevation thereof I Fig. 3 is a vertical section on the line 3'-3 of Fig. 1;

Fig. 41 is a vertical section on the line 4- 4 of Fig. 1;

Fig. 5 is a detail plan view of the stencil guidei'va'y and the means for movingthe st'eneils Specification of Letters Patent.

STENCIL ADDRESSING-MACHINE.

Patented July 16, 1918.

Application filed September 30, 1915. Serial No. 53,285.

. Figs. 6, 7 and 8 are detail plan views of the repeating mechanism; 7 Fig. 9 is a detail sectional View of the repeating selector,

Fig. 10 is a detail in elevation of the inking roller actuating mechanism, and

Fig. 11 is a section on the line 1111 of Fig. 6. I

Referring to the drawings, 1 indicates a base of suitable form and construction to support the various parts of the mechanism as hereafter described. Pivotally mounted thereto on the base 1 is an operating arm 3 provided with a handle .41, whereby the arm 3 may be swung about its pivot 2, the movement being, however, limited by the engagement of a lug 5 on an extension 6 of the arm 3 with the lugs 7 andS on the base 1. A link 9is pivotallysecured at 10 to the operating arm 3 and a bifurcated extension 43 thereof embraces the shaft 26 (Fig. 4). I opposite end with a pivoted pawl 11 normally forced outwardly by a spring 12.

The pawl 11 is adapted to engage a tooth 13 formed on; the end of the bell-crank lever 14, pivotally mounted at 15 on the base 1, thebell-crank lever 14 being normally held in the position indicated in Fig. 1 by a spring 16 secured thereto at. 17 and to the base 1 at 18. The bell-crank lever 14 1s bifurcated at its opposite end, forming arms 19 between which is disposed a cylindrical member 20 rigidly secured to the pin 21 forming a pivot for the toggle links 22 and 23. The 1ink22 is pivotally connected by means of a pin 24 to the inking roller supporting arm 25. The arm 25 is pivotally mounted on a shaft 26 and, as will be readily understood, when the toggle formed by the links 22 and 23 is straightened the arm 25 will be moved about its pivot. A sprmg 25, secured to the arm 25 at 23: and tothe base 1 at 26, normally maintains the arm 25in its uppermost position.

Referringparticularly to Figs. 3 and 1, the togglelink 23 is pivotally connected at 27 withthe platen arm'28 extending transversely of the machine and rotatably mounted on the shaft 29. The platen arm 28 is provided with a platen 29 which is normally disposedin the positie'ti' indicated in Fig. 3,

being held in this position by a spring 30 secured at 31 to the platen arm 28 and to printing position to suppprt receiving material.

In order that. the arm 25 and the platen 29 may be sustained n the 'p t gf 0's1 t on durmg the pr nting operation a dog 35 (see Fig. 1) is pivotally 1no unt ed"at" 3 (i on the base 1 and is adaptedto en get lug 37 on'the bell crank lever 14' and "there by holdlthe toggle in straightened position until the bell crank lever 1435" after the close ofthe printing operation". A spring 38 secured'to the base 1 at 3 9a'nd to the dog 35 at 40,.norinally iirges the dog in the direction of the 37. deg 35 is provided With atail 41 disposed in the path of a i'oller42carriedby the'entension 43 of the link 9 and, asiv'illlbe' readily understood, When thelink is ine vec'l means of the operating arm'3 intofposition to allow the .roller 42 to engagefthe"tail 4l the dog 35 Will release the bell-oral; 'lever 14, allowing springs 16 25 and to break the toggle with the result that tlie'inking-' roller supportingar n and the platen arm 28 return to normal position.

The inking-roller supporting arm 25 is provided at, its extremity with a'pair of tracks or. guideways 44 see 3)"fupo n Which axframe 45, earrying'fthe' inking mechanism, slidably supported. Tliefink ing mechanism comprises-an ink ing" roller 46 having/a smooth resilientsurfaee o'f suitable material such foreX'a'mIpl'e as the composition used in ordinary 'printers'T'ihkP ing rollers. The inking roller 46 is mounted on a shaft 47; which'isisuitablyfjournaled at eitherend in the-framc45l Agear 48 is secured to the shaft. 47 and meshes With a pinion 49 secured to the shaft50, to. Which is also secured a gear 51'ivhich meshes With a rack 52 formed-on the underside of the arm 25 adjacentone of the guidewavs 44. An ink supplying roller 53 is pivotally mountedin the-arms 54 (Fig: 2) seeu edto the. frame 45fby screws 54 The roller 53 is provided with .a surface of felt or other absorbent material which may be saturated with ink and inasmuch as the roller" 53 isdisposed in engagement and v rotates .With' the hiking i'oller 46 a"suffi'cie11t quantity of ink will bet'ransferred to the hiking roller-46 at each printing operation. The roller '46 is maintained in properrelatine, to. the: printing .posiitign. by. means.

spacing Wheels 55 secured to the shaft 47, which are in turn engaged by the spaclng n' heels "56 rotatably'inounted on the sidemembers of the frame 45 and rolling on the undersides of the tracks 44. The frame 45 is connected by means of a link 57 (58616 Fig. 1)- With an extension 58 ofthe link 9 and as the link 9 is reciprocated 'ithe inking roller 46- will be moved longitudinally of the machine While at the same time, as previously explained, the inking-roller supporting arm will, turn about its pivot to carry'the inking'roller 46 downwardly into printing position.

I A magazine 59 is disposed at one end of the bed 1 adjacent the printing position and is adapted to hold a plurality of stencils 60, a iveight fil being provided to maintain the requisite degree of pressure on the-sten cil's" Within the magazine. A pair of grooved guidewa'ys 62 are'secured to .tl'iebed 1 in the plane of. the bottom of magazline 59 and are adapted to support the stencils (3,0

during and folloWin'g the printing o 'jera tion, the stencils beinggu'ided thereby "to a position at. the opposite end'of the machine Where they fall into a receiving magazine 63 disposed beneath the plane'of the gu de waysj' 62. To'movetlie' stencils 60 from the magazine along. the gi ii'deiw ays 621 provide 'a member 64 lslida'bly "mounted in grooves formed inextensions'ofthe guide WayS 62. and lprovided'wigth projecting noses ."i p ed o Pa en a' h the 'iverm t stencil in the magazine 59 and toen'gage the "edge thereof'ivher eupon the stencil G0 forced from the 'magazine 59' thesubsequ'ent operation of the machine and moved alongtheguideivgays 62, into printing position. The actuation of the meinberl 64 is accomplished through a bar rigidlyse cured. thereto and f previdedjvith a shoulder 67adapted tobe engaged "a pawl sepia otally mounted atq69. near the ofthc link 9. A spring 7! secured to the link 9 at. 71 and to the pa vl' GS'at vet rinary the link 9 to the right viewing Fig. 5' independently the-bar when the pawl 68 is disengaged from the shoulder 6 7 As previously pointed out. it is sometimes desirable that the stencils remainiin printing position during two or more operations of the machine in order that a plurality of impressions may be obtained fronr'the stenoils. I have accordingly provided the pawl 63- with an upstanding pin73', herebythe pawl '68 may, through cofiperation oi the pin 7 8 with the mechanism about to be described, be selectively held from engagement with the shoulder 67 or allowed to engage therewith to attain the desired'result.

An upstanding pin 74 is rigidly secured to the end of the link 9. Loosely mounted on the pin 74 is a selector member comprising a cam 7 5' (see Fig. 9 having oppositely disposed arms76, an upstanding cylindrical portion 77 and a knurled head 78. Journaled on the portion 77 is a second cam 79 having a plurality ofteeth 80, the alternate depressions between the teeth 80 being of difierent depth, A pin 81 is secured to the underside of the cam 75 and is adapted to be disposed in one or the other of the openings 82 and 83 in the end of link 9.

The opening 82 does not pass entirely through the link 9 and when the pin 81 is disposedtherein the cam 79 is raised sufficiently to clear the end of the pin 7 3 (Fig. '4), and the arms 76 of the cam 75 are so disposed that they can not engage the pin 73. The pawl 68, is, therefore, not affected by the selector and actuates the bar 66 following each printing operation to dispose a fresh stencil in printing position.

The opening 83 is of suflicient depth to allow the selector to dropv to a position in which the pin 73 is in the pathof the teeth- 80 of the cam 7 9. A'pawl 84 is pivotally mounted at 85 on the base 1 and is normally held bya spring 86 in position to engage the teeth of the cam79 as the link 9 reciprocates. In Fig. 7 of the drawing we have illustrated the pin 73 disposed in a depression of lesser depth between the teeth 80 of the cam 79, the pawl 68 being thereby held from engagement with the shoulder 67 of portion 87 of sufli'cient height to hold the,

the bar 66. At the next succeeding operation of the machine the pawl 84 willengage one of the teeth 80 of the cam 79 and rotate it so that the pin 7 3'will be disposed in the following and deeper'depression between the teeth 80,-allowing the pawl 68 to engagethe shoulder 67 and actuate the bar 66. It will be understood, therefore, that the connection between the link 9 and the bar 66 isalternately made and broken and that, therefore, themember 64 will cause the advance of a stencil from the magazine at each alternate actuation'of the machine. Each of the stencils6O will, therefore, remain in printing positionduring two printing operations so that duplicate impressions may be made.

In order that more than two impressions may be made, if desired, we provide the cam 75, as illustrated in Fig. 8, with a projecting pawl 68 from engagement with the shoulder 67 0f the bar 66 when the portion 87 is so disposed as to engage the pin73. A shallow vopening 88 is provided inthe end of the link 9 which, when engaged by. the pin;

81 on the cam 7 5, maintains the projecting portion 87 of the cam 75 in the desired posi tion of the parts. In this position the pawl 68 is'held from engagement with the shoulder 67'on the bar' 66, hence the member 64 will not be actuated. while this adjustment is maintained and the particular. stencil which is disposed in printing position will remain in this position until the desired number of impressions have been taken and the adjustment is changed to successively feed stencils from the magazine. The operation of the machine should be apparent from the foregoing without further description of the structure. Viewing Fig. 1 at the beginning of the movement of the operating arm 3 to the right the pawl 11 through its engagement with the bellcrank lever 14 causes the toggle, consisting of the links 22 and.23 to straighten, moving the printing-roller supporting arm 25 about its pivot until the inking roller 46 engages the stencil disposed in printing position. Simultaneously the platen 29is moved upwardly to support the impression receiving material beneath the stencil. The dog 35 immediately engages the abutment 37, the hook on the former passing behind the latter to' maintain the parts in printing position against the tensioned spring 16 during the remainder of the printing stroke, during which the inking roller 46 is revolved by the engagement of the gear 51 with the stationary rack 52. The rolling pressure accompanied by sufficient ink to produce the impression is transferred thereby to the stencil. Near the end of the stroke to the right the roller 42 engages the tail 41 of the dog 35 and releases the toggle as previously explained, whereupon the'inking roller supporting arm 25 and the platen 29' are returned to normal position.

Meanwhile, if the selector is adjusted to feed stencils successively after each printing operation the member 64 has been moved to the extreme right, viewing Fig. 5, through engagement of pawl 68 with shoulder 67 of bar 66 and thenoses on the member 64 pass the edge of the lowermost stencil 60 and ii'pon the return movement of the oper ating arm 3 the bar 66, through engagement of the link 9'with the pin 99, is actuated to carry a fresh stencil to printing position. If the duplicating or repeating adjustments have been made the member 64 will operate in the manner previously described to dispose afresh stencilin printing position at each alternate operation of the operating arm 3 or to prevent feeding of the stencils until the adjustment is changed. From the foregoing description it will be apparent that we have succeeded in perfecting a stencil printing machine in which not only is a substantially uniform ink supply assured throughout the printing) operation but-also the operator is enabled, y a simple adjustment and Without manipulating the fromthespiritand scope ofthe invention,

or sacrificing 'any ofits 'material" advantages, the form he'reinbe'fore described being merely a preferred embodimenttliereof.
